Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is a low thermal conductivity thermal insulation core product, specially developed for thermal insulation equipment, high-temperature insulation parts and thermal insulation scenarios. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with thermal insulation fillers and low-thermal-conductivity modifiers, featuring ultra-low thermal conductivity, good thermal insulation, fine uniform closed-cell structure, good elasticity and thermal insulation stability. It has a thermal conductivity of ≤0.03 W/(m·K), low heat transfer, effective heat preservation and insulation, solving the problem of traditional foaming materials’ poor thermal insulation in high-temperature or low-temperature scenarios. Compatible with most of our thermal insulation products, it is ideal for thermal insulation components, heat preservation buffers and thermal insulation scenarios.
